United States Patent 3,447,812 DEVICE FOR BINDING THE HEEL PART OF A SKISHOE Koji Kato, 14-Go, 12-Ban, Higashi-Ogu 4-choxne, Arakawa-ku, Tokyo,Japan Filed July 26, 1967, Ser. No. 656,098 Int. Cl. A63c 9/00 US. Cl.280-11.35 4 Claims ABSTRACT OF THE DISCLOSURE The present inventionrelates to a device for binding the heel part of a ski shoe, andelements thereof, and more particularly, to a metalfixture for fittingthe boot easily in its entirely to the ski by binding its heel part.

The object of this invention is to provide a step-in type heel bindingdevice for a ski shoe which can fix and retain effectively and suitablythe heel part of a shoe to the ski with extreme ease and smoothness andwhich is adapted so as to be capable to adjust the mounting position ofthe boot and also the compression position for the heel part of theboot.

The present invention will be better and further understood and otheradvantages of the invention will become apparent from the followingdescription of one embodiment of the invention and in connection withthe appended drawing, in which:

FIG. 1 is a side view of the embodiment of the invention;

FIG. 2 is a side View thereof wherein an upper frame is shown invertical section;

FIG. 3 is a plan view thereof;

FIG. 4 is a plan view thereof wherein the upper frame is shown incross-section; and

FIG. 5 is a frontal view thereof.

Referring to the drawing, there is provided a carrier plate 3 which isengaged in rails 2 formed by bending both sides of a base plate 1; anengaging channel 4 is provided at the lower end of said carrier plate 3between frame plates 3'; an anchoring pin 7 provided with an auxiliaryframe 6 having a bent wall part 5 is engaged in said engaging channel 4;a lever handle provided with a fitting pin 8 and a receiving pin 9located between the frame plates 3' of the carrier plate 3 is pivotallysupported by pin 11; there is provided a coil spring 12 obliquelyanchored and connected between the receiving pin 9 and the anchoring pin7. There are provided a heel receptacle 1'4 and a heel presser on oneside of an upper frame 13; said heel presser 15 is adapted so as to bevertically adjustable; a plastic body 16 such as hard nylon or the likeis held on the upper face and the inside of said upper frame 13; andfurther there is provided an anchoring block 18, with a fitting channel17, pivotally supported at pin 19; the upper frame proper 20 thus formedis pivotally supported at pin 21 together with the carrier plate 3 inconformity with the frame plates 3 of said carrier plate 3. There isconstituted a bent wall part 22 at the end of the base plate 1; saidbent wall part 22 and the bent wall part 5 of the auxiliary frame 6 areconnected through an adjusting screw 24 having a left screw thread 23 onone end and a right screw thread 23' on the other.

In the drawing, numeral 25 denotes screw holes; nu-

meral 26 denotes a stop screw; numeral 27 denotes a nut; numeral 28denotes a slot; numeral 29 denotes a hook; numeral 30 denotes anadjusting nut firmly fitted to the adjusting screw 24; numeral 31denotes a nut for fixing the adjusting screw 24; and numeral 32 denotesa window part for swinging the lever handle 10.

Such being the composition of the embodiment of this invention, theoperation thereof will now be given as follows:

In the first place, the device is securely fixed with screws to aspecified position of the ski, whereafter the lever handle 10 is pusheddown as is shown in chain dotted lines in FIG. 2. When the fitting pin 8of the lever handle 10 is released from the anchoring block 18 and theupper frame proper 20 is turned, the lower end of the anchoring block 18will abut the fitting pin 8 and said upper frame proper 20 will faceupward and come to be set in the position as is shown in chain dottedlines in FIG- URES 1 and 2. The heel of the boot is then mounted on theheel receptacle 14 provided on one side of said upper frame proper 20,which receptacle is thence depressed, and the curved part 18' of theanchoring block 18 will push the lever handle 10 down through its actionon the fitting pin 8. The upper frame proper 20, thereupon, will turn sothat the heel presser 15 comes to press against the rear part of theboot so that the same is smoothly and securely fixed to the ski. At thesame time, the fitting channel 17 of the anchoring block 18 will come toreceive the fitting pin 8, and the lever handle 10 will be in tensionconstantly by virtue of the coil spring 12 obliquely connected andanchored between the anchoring pin 7 and the receiving pin 9, so that itis so adapted that the normal fitting condition of the anchoring block18 with the fitting pin 8 is invariably maintained. Composed in thismanner, the boot may be perfectly fixed and retained on the ski, inaddition to the fact that there is not the slightest fear ofdisengagement of the anchoring block 18 with the fitting pin 8 eventhough there occur vertical, horizontal or other vibration or shocksduring ski running, so that skiing can be enjoyed comfortably and withsecurity.

Further, the heel presser 15 for the boot is devised so that it can bevertically adjusted against the upper frame proper 20 by means of thestop screw 26, and therefore, it is shiftable to any position suitableto a boot of any size, thereby making it possible to fix the boot to theski under the optimal condition. On the other hand, the adjusting screw24 which connects the bent wall part 22 of the base plate 1 with theauxiliary frame 6 can be rotated by the adjusting nut 29; the carrierplate 3 may be shifted and set through the auxiliary frame 6 up to anypoint suitable to the users boot, and consequently, the boot may beoptimally fixed and held. As the present device is so composed that theadjusting screw 24 is provided with the left screw 23 and the rightscrew 23' so as to be constituted in different shapes on both ends ofthe screw and the adjustable shifting range of the carrier plate 3 isextremely large, said carrier plate 3 can be moved and adjusted to thesize of the boot and thus can be set at any point in conformity with theboot, and therefore the device may be used regardless of the size ofboots.

When the ski boot is to be removed, this is achieved by downwardlydepressing the end of the lever handle 10 between the frame plates 3' ofthe carrier plate 3 with the tip of a ski stock or by hand; disengagingthe fitting of the anchoring block 18 provided with the upper frameproper 20 with the fitting pin 8 of the lever handle 10; and thereafter,just simply turning the upper frame proper 20.

As described in the foregoing, the present invention is extremelyadvantageous and meritorious in comparison to the conventional means,especially, of reliably fixing and holding the ski boot to the ski, andsmoothly and rapidly effecting the fixing as well as removing the boot.

What I claim is:

1. A device for binding the heel part of a ski boot, said devicecomprising a base plate adapted for being secured to a ski and havingbent ends forming rails, a carrier plate slidably engaged in said railsand including a frame plate having a channel, an anchoring pin engagedin said channel, an auxiliary frame secured to said pin, a leverpivotably mounted on the carrier plate and including a fitting pin and areceiving pin thereon, a coil spring secured to said anchoring pin andsaid receiving pin the position of the latter pins being such that thespring has an inclined position, an upper frame member pivotallysupported from said carrier plate for movement between a raised unlockedposition and a lowered locked position, a heel receptacle and a heelpresser secured to said upper frame, an anchor block carried by saidupper frame and having a channel for receiving the fitting pin on saidlever when the upper frame is in its lowered locked position, and meansbetween said base plate and auxiliary frame for connecting the same together with adjustment whereby the position of the upper frame andthereby of the heel receptacle and heel presser relative to the baseplate.

2. A device as claimed in claim 1 wherein said means between the baseplate and auxiliary frame comprises an adjustment screw including firstand second threaded portions of opposite hand respectively engaged insaid base plate and anchoring frame.

3. A device as claimed in claim 1 wherein said anchor block includes alower curved portion which abuts against said fitting pin in the raisedposition of the car-' References Cited UNITED STATES PATENTS 3,125,3493/1964 Schweizer 280-11.35 3,317,217 5/1967 Poiger 280-1135 3,278,19510/1966 Salomon 280-1135 3,333,859 8/1967 Smolka et al 280-11353,366,394 1/1968 Shimizu 2801l.35
